Sin is serious because you are called to do something great in the world, and sin makes you and me less than what we are called to be.
Jesus is not a security blanket, let Him challenge you.
We need to encounter Jesus in a profound way, and we need to be united in an authentic community.
Don't compartmentalize your relationship with Jesus.
